Abstract
The present invention provides an industrial robot which can reduce torque required for driving an object to be moved. By providing a third reduction device and a third driving device separately, the dimension in the third axial direction of the third reduction device can be reduced, thus the distance from a second axis to an end effecter can be decreased. As such, the torque required for a first driving device and a second driving device to rotate and drive the end effecter can be reduced. Accordingly, even when the weight of the end effecter is increased, an increase of the torque required for the first driving device and the second driving device can be suppressed. Therefore, a higher speed operation can be achieved as compared with the conventional industrial robot.
